Die Vorteile der vorliegenden Erfindung sind Folgende.The advantages of the present invention are as follows.
Viskositäten werden häufig mit einem Penetrometer gemessen. Bei der Messung wird ein kegelstumpfförmiger Gegenstand manuell auf die zu messende Substanz gesetzt. Von dem kegelstumpfförmigen Gegenstand erstreckt sich ein länglicher Schaft, der als Führung für ein entlang des Schaftes beweglich angeordnetes Gewicht dient. Das Gewicht wird nun aus vorbestimmter Höhe entlang des Schaftes auf den kegeistumpfförmigen Gegenstand fallengelassen, wodurch dieser in die zu messende Substanz eindringt. Im Bereich der Spitze des Kegelstumpfs sind Ringe angegeben, welche die Penetration, das heißt die Eindringtiefe des Kegelstumpfs in die Substanz anzeigen. Je geringer die Penetration ist, desto viskoser ist die Substanz.Viscosities are often measured with a penetrometer. In the measurement, a frusto-conical object is placed manually on the substance to be measured. Extending from the frusto-conical object is an elongated shaft which serves as a guide for a weight movably mounted along the shaft. The weight is now dropped from a predetermined height along the shaft on the keI-truncated object, whereby this penetrates into the substance to be measured. In the area of the tip of the truncated cone rings are indicated, which indicate the penetration, that is the penetration depth of the truncated cone in the substance. The lower the penetration, the more viscous the substance is.
Mit Hilfe der hier beschriebenen Vorrichtung können aktive Massen mit einer Penetration in einem Bereich von ca. 20-22, insbesondere 22 in Röhrchen eingefüllt werden. Bei der Bestimmung dieser Penetration beträgt das Gewicht des Fallkörpers 300g und das des kegelstumpfförmigen Eindringkörpers 175g. Die Fallhöhe ist 67mm. Der Kegelstumpf hat einen oberen Durchmesser von 20mm und einen unteren Durchmesser von 9mm an der Eindringseite. Die Höhe des Kegelstumpfes beträgt 113mm. Der Kegelwinkel (2ϕ) beträgt ca. 5,6°. Die Temperatur, auf die sich die voranstehend erwähnte Penetration bezieht, ist ca. 50°C.With the aid of the device described here, active masses having a penetration in a range of about 20-22, in particular 22 can be filled into tubes. In determining this penetration, the weight of the drop body is 300g and that of the truncated cone is 175g. The drop height is 67mm. The truncated cone has a top diameter of 20mm and a bottom diameter of 9mm on the penetration side. The height of the truncated cone is 113mm. The cone angle (2φ) is approx. 5.6 °. The temperature on the the above-mentioned penetration is about 50 ° C.
Wird die erste Fördereinrichtung 1, das heißt die erste Exzenterschneckenpumpe 1 über eine relativ lange Rohrleitung mit dem Füllsammelrohr 3, 3' verbunden, muss die Pumpe 1 mit sehr hoher Druckleistung betrieben werden, um längs des Füllsammelrohrs 3, 3' einen Druckgradienten zu vermeiden, der sonst zu einer ungleichmäßigen Befüllung der Geweberöhrchen führen würde. Um dieses Problem zu vermeiden, haben verschiedene Hersteller von Bleiakkumulatoren die Viskosität der aktiven Masse einfach verringert (Penetration 58). Der Erfinder der vorliegenden Erfindung hat allerdings herausgefunden, dass die aktive Masse, die in pastöser Form in die Geweberöhrchen eingebracht wird, eine möglichst hohe Viskosität aufweisen sollte. Denn eine Verringerung der Viskosität hat einerseits einen relativ hohen Materialaustritt aus den Geweberöhrchen und im Anschluss eine zeitaufwendige Waschprozedur, und andererseits eine inhomogene Füllung der Geweberöhrchen zur Folge. Um bei hoher Viskosität (Penetration 20-22) eine gleichmäßige Druckverteilung Innerhalb des Füllsammelrohrs 3, 3' sicherstellen zu können, wird gemäß der Erfindung mindestens eine weitere Fördereinrichtung 2a, 2b, 2a', 2b' zwischen der ersten Fördereinrichtung 1 und dem Füllsammelrohr 3, 3' zwischengeschaltet.If the
Mit der vorliegenden Erfindung können hochviskose (Penetration 20-22) aktive Massen in die Geweberöhrchen eingebracht werden. Dadurch ist der Füllgrad in sämtlichen Geweberöhrchen einheitlich, was zu einer hohen spezifischen Leistungsfähigkeit, niedrigen Innenwiderständen und einer extrem langen Lebensdauer der positiven Plattenelektrode führt. Ebenso wird nahezu die gleiche Menge an aktiver Masse in jedes Geweberöhrchen eingebracht, was zu einer gleichmäßigen Beanspruchung der aktiven Masse in sämtlichen Geweberöhrchen führt. Dadurch, dass aktive Massen mit relativ niedrigem Feuchtigkeitsgehalt abgefüllt werden können, erhält man eine dichte Kontaktierung mit den zentral in den Geweberöhrchen geführten Bleiseelen der Elektroden. Dadurch werden die einzelnen Röhrchenelektroden sowohl untereinander als auch in der Längsrichtung gleichmäßig beansprucht. Durch die intensive Kontaktierung zur Bleiseele wird dieselbe nicht zerformiert und verformt, so dass eine Expandierung der Bleiseele über die gesamte Lebensdauer des Bleiakkumulators vermieden wird. Hieraus werden eventuell auftretende Verformungen des Deckels des Bleiakkumulators durch expandierte Bleiseelen vermieden, wodurch auch eine fehlerfreie Funktion der Wassernachfüllventile im Deckel des Bleiakkumulatorgehäuses gewährleistet ist. Durch die gleichmäßige Befüllung und dadurch bedingt eine gleichmäßige Dichte in den Geweberöhrchen untereinander werden auch sog. Säureschichtungen vermieden.With the present invention, highly viscous (penetration 20-22) active masses can be introduced into the tissue tubes. As a result, the degree of filling in all the tissue tubes is uniform, resulting in high specific performance, low internal resistance, and extremely long positive electrode plate life. Similarly, nearly the same amount of active mass is introduced into each tissue tube, resulting in a uniform loading of the active mass in all tissue tubes. By filling active masses with a relatively low moisture content can be obtained, a dense contacting with the centrally in the tissue tube led Bleiseelen the electrodes. As a result, the individual tube electrodes are stressed uniformly both with each other and in the longitudinal direction. Due to the intensive contact with the lead cores, the same is not formed and deformed, so that an expansion of the lead cores over the entire life of the lead accumulator is avoided. From this, possibly occurring deformations of the lid of the lead-acid battery are avoided by expanded Bleiseelen, whereby an error-free function of Wassernereinfüllventile is ensured in the lid of the lead-acid battery housing. Due to the uniform filling and therefore a uniform density in the tissue tubes with each other and so-called. Acid coatings are avoided.
Durch die zweite Fördereinrichtung 2a, 2b, 2a', 2b' wird ein definierter Fülldruck unmittelbar am Füllende, vorzugsweise an beiden Füllenden des Füllsammelrohres 3 (
